Hanovia’s PureLine Ultraviolet Energy Optimised (UVEO) medium pressure UV system uses up to 60% less power than conventional UV systems with just a single UV lamp. This delivers a guaranteed, consistent UV dose with reduced life cycle costs for the food, beverage and brewing industries.

Energy and cost reductions
Building on Hanovia’s 90 years’ experience in UV treatment, the PureLine UVEO takes advantage of an optimised hydraulic design to provide up to 60% improvement in the treatment capacity over conventional medium pressure UV systems. This means reduced running costs without compromising on bio-security.

A prime benefit is that treatment is performed with just a single medium pressure UV lamp, eliminating the need to install a bigger system with multiple lamps at higher flows. This saves on up front capital costs and lifetime spares costs.

The system utilises a smart control system that reads the process water conditions using flow, transmittance and chlorine sensors to control the electronic ballast with ‘stepless’ power, which can then automatically adjust the power from 100% to 30%. This feature helps increase the life of the medium pressure lamp and provides further savings on power costs.

Designed for the food and beverage industries
PureLine UVEO systems come in three ranges:

  • The ‘H’ Edition is designed specifically to meet the highly stringent food, beverage and brewing industry regulations. All wetted parts use food grade-approved materials, while a UV chamber with a high specification internal finish is available if required
  • The ‘Standard’ edition, which provides required levels of disinfection and prevents downstream contamination before reverse osmosis (RO) filters and at the point of use
  • The ‘Dechlor’ edition, based on either H or Standard chamber designs, which provides guaranteed levels of dechlorination coupled with strong disinfection to protect downstream processes such as Reverse Osmosis (RO) from premature aging and biofouling

Medium pressure UV lamps provide the highest possible UV output at the specific wavelengths required to destroy microorganisms. Medium pressure UV is especially effective against chlorine-resistant pathogens such as Cryptosporidium and Giardia. Reduced reliance on chlorine helps protect downstream contamination of filters early on in the water treatment process. Medium pressure UV is also very effective at removing ozone from process water, ensuring product quality before bottling.

UVEO technology provides the food, beverage and brewing industries with optimised UV systems in line with requirements. The PureLine UVEO’s chamber size, lamp power and control systems have been tested to ensure not only that high levels of process water disinfection are achieved, but also that green initiatives are met by lowering power consumption.

Safe, easy maintenance
The PureLine UVEO is provided with Hanovia’s patented ‘UVGuard’, which allows safe checking of the UV sensor (performance monitoring instrument) using a unique ‘eyelid shutter’ design, which protects the operator from exposure to UV light.

The UV system is available in a range of sizes and treatment capacities to meet typical process requirements. It is designed for easy installation into existing pipework and can be fitted with an internal auto-wiper which maintains UV output efficiency by regularly cleaning the quartz sleeve housing the UV lamp. Lamp replacement is also quick and easy, with the system designed to allow easy access, even in small plant rooms.

To disinfect water in the winemaking process, Brown Brothers winery in Victoria, Australia has installed a Hanovia ultraviolet (UV) disinfection system. The system was installed by Fluidquip Australia, Hanovia’s local partner.

One of Australia’s leading family-owned wine companies, Brown Brothers has been making wine in Victoria for over 120 years. Over this time it has established a reputation as one of Australia’s most innovative wine producers.

Being a fourth generation family winery, it’s seen many changes in the Australian wine industry, yet the cornerstone of its success remains as a varietal wine specialist and winemaking innovator.

With this mantra in mind, the company selected Hanovia UV disinfection to treat the water needed for its wine-making process. UV delivers the most secure and environmentally friendly water disinfection available, with the UV-treated water used for bottle washing, process water, QC, laboratory water and just about anything else where clean and bio-secure water is required throughout the winery.

In 2009 Brown Brothers updated its existing UV water disinfection system to the latest Hanovia AF3 UV system. “Our Hanovia UV system has worked perfectly since we installed it in 2009. We routinely get a zero (bacterial) count after the UV. It wasn’t always that way – our old UV system would often return counts for bacteria of 40, 80 or sometimes even 100 CFU (Colony Forming Units),” says Steve Dows from Brown Brothers.

The Hanovia UV disinfection system safeguards Brown Brothers’ water from the risk of water-borne micro-organisms such as bacteria, viruses, yeasts and moulds, as well as harmful protozoa such as Cryptosporidium and Giardia, which are chlorine-resistant. It does this with no effect on the water’s pH, colour or taste, ensuring there is no impact on the quality, flavour or aroma of the wine, which is important when you are producing gold medal winning wines.

“Chlorine is a no-no anywhere in the wine making process as it can affect the taste of the wine,” adds Steve.

Brown Brothers use a deep bore as its water supply and positions the Hanovia UV disinfection system after 0.04 micron filters. UV disinfection has the advantage of using no chemicals and it introduces no disinfection by-products into the process. It is effective against all known microbes.

After being awarded several gold medals in the Royal Melbourne Wine Show in 2012, it’s clear that Brown Brothers continue to lay claim as one of Australia’s most iconic winemaking success stories.

Malaysian Soft Drink Manufacturer uses Hanovia UV to Remove Bacteria from Process Water

F&N logo

UV disinfection system installed after dechlorination unit

F&N Beverages Manufacturing Sdn Bhd in Malaysia has installed a Hanovia UV disinfection system at its state-of-the-art manufacturing plant in Inanam, Kota Kinabalu. The Hanovia UV system is installed after an activated carbon dechlorination unit and is used to eliminate bacteria from water used in the soft drinks manufacturing process.

F&N is Malaysia’s largest soft drinks manufacturer, producing many of the country’s most well-known brands, including 100PLUS, F&N Fruit Tea and F&N SEASONS. The company’s brand promise is ‘Pure Enjoyment, Pure Goodness’, so quality is uppermost in all its manufacturing processes.

UV technology is required for this application to fulfil local QA/QC (quality assurance/quality control) requirements. Hanovia was selected as the UV system supplier due to the company’s reputation in the beverage industry and the fact that its UV systems are optimised for process water applications such as those found in beverage manufacturing. Added benefits for the customer included low operating and maintenance costs.

The benefits of UV
Meeting the increasingly rigorous hygiene standards required in the beverage industries is a real challenge. If improvements need to be made to plant and equipment, they need to bring quick returns on the investment and measurable improvements in product quality.

For manufacturers seeking to improve the quality of the end product, UV is an economic, realistic option. It is an established method of disinfecting drinking water throughout the world, and is also widely used for high purity applications such as pharmaceutical processing and microchip manufacturing, where water of the highest quality is essential.

There are no microorganisms known to be resistant to UV – this includes pathogenic bacteria such as Listeria, Legionella and Cryptosporidium (and its spores, which are resistant to chlorination).

UV disinfection systems are also easy to install, with minimum disruption to the plant. They need very little maintenance, the only requirement being replacement of the UV lamps every 9 – 12 months, depending on use. This is a simple operation that takes only a few minutes and can be carried out by general maintenance staff.

PureLine PQ uses either low pressure high output or medium pressure lamps to safely disinfect water passing through the system, exposing it to UV light and deactivating any microorganisms present. All systems feature an automatic wiper to automate optical path maintenance, further reducing operating expenses.

The Dairy Plus Co. Ltd. in Thailand has recently replaced its chlorine-based disinfection system with five PureLine PQ UV systems – four duty and one standby. Two units disinfect clean-in-place (CIP) water and two are used for treating dairy mixing water, with each system treating up to 130m3/hour of water. Dairy Plus decided to reduce high levels of chlorine dosage throughout the process because it was proving ineffective at removing all microorganisms, particularly in the rainy season. It was also producing an after-taste in the product.

“Since our UV systems were installed the customer is very satisfied and reports excellent disinfection results,” commented Ying Xu, Hanovia’s Asia-Pacific Sales Manager. “Dairy Plus is particularly impressed by the low maintenance costs, the high energy output of the systems and the fact that the frequency of CIP procedures has been dramatically reduced, meaning less down-time of the manufacturing process”.

Hanovia is celebrating its 90th anniversary this year! From its early days manufacturing UV lamps to treat skin conditions to today’s validated, performance qualified UV water treatment systems, the company has always been a technology leader and at the at the forefront of UV innovation.

Using UV Disinfection to Ensure Bio-Security in the Pharmaceutical, Food and Beverage Industries

The pharmaceutical and food & beverage industries are unique in that their products are either consumed directly or are used in products that are actively consumed by people. In an increasingly regulated and safety-conscious market, these industries have to meet ever more stringent standards on water quality and bio-security.

It is vital to treat the water used in the manufacturing process to remove toxins, biohazards and any unwanted organic materials, while at the same time not incurring any residual taste, colour or reagents that could affect another part of the downstream process. In these industries the ‘raw’ potable water they source at the start of the process may not be completely free of bio-challenges, as needed for their individual processes, resulting in active growth of microorganisms to harmful levels.

UV disinfection for processing

UV disinfection for processing

UV is ideal for these applications as it is both effective and chemical-free. It eliminates all known pathogenic and spoilage microorganisms, including bacteria, viruses, yeasts and moulds (and their spores) and is low maintenance and environmentally friendly.

In this article Mark Aston, Hanovia’s Technical Manager, discusses the importance of UV in ensuring bio-security.

The importance of bio-security
Bio-security is very important to understand from both the supplier and customer perspective. It is a fine balancing act between providing an appropriately-sized treatment system on the one hand while ensuring viable cost of ownership on the other.

Where a UV system is required to target a specific bacteria, virus or other bio-hazard, the precise minimum dose needed to achieve the required reduction of that hazard must be well characterised and monitored in delivery. Three general types of system can be used for this task:

  • Very cost-effective systems monitored for a minimum lamp intensity that achieve a minimum delivered dose which is not defined
  • Cost-effective systems that have been referenced to known validations and therefore offer an assured bio-security, but without the absolute cost of a full validation
  • Costly systems that have been fully validated to monitor the precise dose delivered and the power of the system controlled to continually deliver that required dose

How UV disinfection works
UV is the part of the electromagnetic spectrum between visible light and X-rays. The specific portion of the UV spectrum between 185-400nm (known as UV-C) has a strong germicidal effect, with peak effectiveness at 265nm. At these wavelengths UV eliminates microorganisms by penetrating their cell membranes and damaging the DNA, making them unable to reproduce and effectively killing them.

A typical UV disinfection system for process water or liquid ingredient consists of a UV lamp housed in a protective quartz sleeve and mounted within a cylindrical stainless steel chamber. The liquid to be treated enters at one end and passes along the entire length of the chamber before exiting at the other end. Virtually any liquid can be effectively treated with UV, including raw mains water, filtered process water, viscous sugar syrups, beverages and effluent.

There are no microorganisms known to be resistant to UV; this includes pathogenic bacteria such as Listeria, Legionella and Cryptosporidium (and its spores, which are resistant to chlorination).

UV dose
The UV dose necessary for microbial deactivation varies from one species to another and is measured in millijoules per square centimetre (mJ/cm2). Values for specific microorganisms have been experimentally established and are used to determine the type and size of UV system required.

The dose received by an organism in a UV treatment system is dependent on four main factors:

1.    The energy output of the UV source
2.    The flow rate of the fluid through the treatment chamber
3.    The transmission value (ability to transmit UV light) of the fluid being treated
4.    The geometry of the treatment chamber

By optimising these criteria, a UV system can be tailored to effectively treat large or small flows, as well as viscous fluids or those containing dissolved solids and high levels of starch or sugar compounds.

UV technologies
There are two main types of UV technology based on the UV lamps used: low pressure and medium pressure. Low pressure lamps have a ‘monochromatic’ UV output (limited to a single wavelength at 254nm), whereas medium pressure lamps have a ‘polychromatic’ UV output (between 185-400nm).

As UV has no residual effect, the best position for a treatment system is immediately prior to the point of use. This ensures incoming microbiological contaminants are destroyed and there is a minimal chance of post-treatment contamination.

UV applications in the pharmaceutical, food and beverage industries
Direct contact water
Although municipal water supplies are normally free from harmful or pathogenic microorganisms, this should not be assumed. In addition, water from private sources such as natural springs or boreholes could also be contaminated. Any water used as an ingredient, or that comes in direct contact with the product, can therefore be a source of contamination. UV disinfects this water without chemicals or pasteurisation. It also allows the re-use of process water, saving money and improving productivity without risking the quality of the product.

CIP (Clean-in-Place) rinse water
It is essential that the CIP final rinse water used to flush out foreign matter and disinfecting solutions is microbiologically safe. Fully automated UV disinfection systems can be integrated with CIP rinse cycles to ensure final rinse water does not reintroduce microbiological contaminants.

Filter disinfection
Reverse osmosis (RO) and granular activated carbon (GAC) are often used to filter process water, but can be a breeding ground for bacteria. UV is an effective way of disinfecting both stored RO and GAC filtered water and has been used in the process industries for many years.

GAC filters are also often used to dechlorinate process water, removing the ‘off’ flavours often associated with chlorine disinfection, meaning the flavour of the final product remains untainted and free from unwanted flavours or odours. Placing UV systems ahead of GAC filters used for dechlorination improves the performance of the filters and results in longer carbon runs, so decreasing operating costs.

As the usual dose for removing free chlorine is 15 to 30 times higher than the normal disinfection dose, an important additional benefit of using UV dechlorination is a high level of UV disinfection, reduction in Total Organic Carbon (TOC) and improved overall water quality at point-of-use.

TOC reduction
Short UV wavelengths (below 200nm) are highly effective at breaking down organic molecules present in water, commonly known as Total Organic Carbon (TOC), especially low molecular weight contaminants. This works in two ways: the first method is by direct photolysis, when energy from the UV actually breaks down chemical bonds within the organics; the second method is by the photolysis of water molecules, splitting them to create charged OH- radicals, which also attack the organics.

Cooling media and chiller disinfection
Some meat and dairy products are subject to contamination after heat treatment or cooking. UV provides an excellent way to protect foods from contamination by contact-cooling fluids.

Sugar syrups
Sugar syrups can be a prime breeding ground for microorganisms. Although syrups with very high sugar content do not support microbial growth, any dormant spores may become active after the syrup has been diluted. Treating the syrup and dilution water with UV prior to use will ensure any dormant microorganisms are deactivated.

Liquid sweeteners
Sucrose-based sweeteners can be a prime breeding ground for microorganisms. UV systems are available specifically for treating these syrups.

De-aerated liquor
De-aerated liquor is added as part of a high gravity brewing process, often in the packaging operation. This liquor is added directly to the beer so needs to be kept free from contamination by gram negative bacteria, which can cause off-flavours and acidity.

Yeast preparation
The problems associated with yeast preparation in breweries are well recognised and include hazes, altered fermentation and surface membranes on packaged beer. A single cell of Sacchoromyces (var. Turbidans) in 16 million cells of pitching yeast will cause detectable hazes. UV destroys all known yeasts and their spores.

Waste water
Effluent from pharmaceutical, food and beverage facilities can be treated without the use of environmentally hazardous chemicals. This ensures all discharges meet with local environmental regulations. As already mentioned, because process water can be treated and re-used with UV, this also leads to a significant reduction in the amount of waste water produced.

Meeting the increasingly rigorous hygiene standards required in the production of pharmaceutical, food and beverage products is a real challenge. If improvements need to be made to plant and equipment, they need to bring quick returns on the investment and measurable improvements in product quality.

For manufacturers seeking to improve the quality of the end product and to ensure the bio-security of their process, UV is an economic, realistic option. It is already an established method of disinfecting drinking water throughout the world, and is already widely used for high purity applications where water of the highest quality is essential.

UV disinfection systems are easy to install, with minimum disruption to the plant. They need very little maintenance, the only requirement being replacement of the UV lamps every 9 – 12 months, depending on use. This is a simple operation that takes only a few minutes and can be carried out by general maintenance staff.
